In comparison to what? If you are talking about the Sport Line seats - they are the same. Only difference between the M-Sport/Sport Line seats and the Luxury/Modern line is the absence of the extendable thigh rest and adjustable side bolsters.

From what I remember driving them is that the M-Sport and Sportline are the same in seat design - if that's what you are asking.

Cosmetically if you get M-Sport, the seats are either black leather seats ( LCSW ) or Coral Red ( LCL5 ). You can't get the black seats with red piping ( LCL3 ) in M-Sport. You can only get that in Sport.

Sport seats felt much more supportive. I feel like i am deeper in the bucket with larger side bolsters.
